When enjoying extra hours once again, my friend Ken and I mentioned a word we saw on our high-end watches "Caliber". He told me that every top watch brand attached the word onto there most complicated products to show their high qualities. Then I began to search the meaning of the word. Here are some result from search engine of Wikipedia:
In architecture, the caliber of a column is its diameter.
In electricity, the caliber of an instrument of measure is the maximum value it can measure.
In nautical parlance, the caliber of a chain is the diameter of the metal rod used to make each chain link.
In typography, the caliber of a font designates the size of the eye of a character, neglecting any risers or descenders.
Colloquially, the term "high caliber" is used to refer to people or employees of great competence or ability.
